MACHINE FOR MAKING PAPER TUBES.

Specification of Letters Patent.

Application led March 16, 1910. Serial No. 549,761.

To al? whom 'it may; concern.

Bc it known that I, FRANK E. KEYES, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Making Paper Tubes; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionrelates to im rovements in machines for making paper tu es, the object of the invention being to provide simple and efficient means for removably and adjustably supporting the shafts or cores on which the paper forming the tubes is wound.

lVith this object in view, the invention consists in certain novel features ot' construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation showing a portion of a tube making machine illustrating the application of my improvements thereto; Fig. 2 is an enlarged face view of one of the spiders which carry the roll or core supporting devices; Fig. 3 is a transverse sectional view showing the arrangement of the spiders on the shaft which carries them; Figs. 4 and 5 are enlarged detail views of the devices which carry the rolls or cores on which the paper is wound, and Figs. 6 and 7 are sectional views on the lines -m and g/-y respectively of Fig. 2.

1 represents a portion of the frame-work of a tube making machine, and 2 the couch roll of said machine, or the mold roll in case no couch roll is used. yStandards 3 rise from the top of the frame or casing 1 and are made at their upper ends with integral yokes 4 in which bearing brackets 5 are located for the accommodation of the journals 6 of a shaft 7 which carries the supporting means for the winding rolls or cores on which the paper is wound. Each bearing bracket is provided with a series of elongated slots 8, into which guide pins 9 project. At the lower end of each bracket, a lug 10 is provided and has swiveled thereto, the upper end of a screw 11. Each screw 11 passes through a threaded hole in 'a flange 12 and at its lower end, each screw is provided with a hand wheel 13. The standards 3 are provided at their upper ends with arms 14, to

vwhich levers 15 are pivotally connected between their ends. The short arms of the levers are made hook-shaped to engage under the shaft 7 and the long arms of said levers are provided with weights 16 which serve to eounterbalance the winding rolls or cores and their supporting devices and prevent excessive pressure upon the couch or mold roll or shell 2. To the shaft 7 two spiders 17 are secured, each spider comprising a series of radial arms 18 and connecting or bracing webs 19. Each radial arm 18 is made in its outer portion with an elongated slot 2O for the accommodation of a journal 21 of one of the winding rolls or cores 22.

Shoulders l23 are located at respective sides of the slot and extend from end to end of the arm. That portion of each arm 14 in rearv of the slot 20 is depressed, as shown at 24 and this depressed portion of each arm is provided with an elongated slot 25. A bar 26 is disposed on each arm 14, and to this bar a spring plate 27 is secured by means of bolts 29, said plate being somewhat less in width than that of the bar. The bar rests on the shoulders 23 and a bolt 30 passes through each bar 26, and also through the elongated slot of 'one of the arms 18, thus adjustably connecting the bars and their springs to the spider arms. The outer end of each bar 26 is provided with a curved enlargement 31 for the accommodation of a journal 21 of one of the winding rolls or cores 22 and prevents displacement of the latter toward the center of the spider. Each spring 27 is made of suiiicient length to extend past the end of journal 21 and has se cured toits -free end, a curved lug or bearing 32 which receives journal 21 and prevents release of the winding roll. Each lug or bearing 32 is provided with a 33, by means of which the spring 27 and lug or bearing 32 carried thereby7 can be moved outwardly to release the journal 21 and thus permit the removal of the winding roll.

The spiders will have a series of winding rolls mounted therein and these adjusted that one of saidwinding rolls will be so located as to eoperate with the couch or mold roll 2 to receive paper therefrom, and will be retained in such position, by means of pins 34, against which, one of the arms 18 carrying the active winding roll,

It will be readily seen tha making the Vbars 2G and springs '127 longitudinallyadjustablc with respect to the arms of the i spiders, the .windinfr rolls can he set for making;V tubes of diif-erent thicknesses.

Havingf'fully described my invention what I clamasnew and desire to secure by Letters-Patent, isr- 1. In a Inachlne of the lcharacter described,

kthe combination ywith a shaft and armsthereon, of spring plates attached to said arms f andconstructed at their free ends to form bearingsfor the journals ofwinding rolls.

2. In a machine of the character described,

" for the journals of a winding roll.

In a machine ofthe character described,

vthe coi'nbination with a shaft and spiders on said shaft, each of said spiders having a series of radiating arms, of a Spring plate securedwto each of said arms andV provided at its outer end with a bearing for the journal of a Winding roll. Y

4. In aniachine of the charactery described, the combination with a shaft and arm thereon, of a bar adjustable on-said arm and having a journal bearing, a spring plate secured to said adjustable bar, a bearing for the journal of a winding roll at the outer end of said spring plate, and a linger piece connected with the bearing` on the spring for withdrawing the same tomove it relatively said journal.

` 5.' In vamachine of the character described,

the combination with a shaft and, spider thereon comprising),` radial arms, of a bai' adjustably secured to each arm, a spring plate secured toeach bar, and a bearing at the free end of each spring' plate, for Aa.

In amachine of the character described, the combinatlon with a shaft, and arms projectingftherefrom, each of said arms having open slots for the reception of journal` bearings of a winding rol mounted on each arm, a bolt passing through each bar and closedelongated slot, a spring plate secured to each bar, and a bearing at the free endof each s ring plate, for a jour- -nal of a winding rol 7. In a machine of the character described, the combination with a shaft and two spiders thereon, each having a series of radiating arms, of a baradjustably mounted on each of said arms, a spring plate secured to each bar, a bearing lug at-,the freefend of each spring plate for the accommodation of a connected with each of said bearing lugs.

8. In a machine of the character described, the combination with weighted levers, and a shaft sustained thereby, of two spiders secured to said shaft,`each spider comprising a series of radial arms, spring plates adjustably secured to the'arms of the spiders, and retractile meansv at the free ends of said spring plates for supporting the journals of a series of Winding` rolls.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.-
